The manhole cover hit the tunnel floor with a clang that Aaron felt in his back teeth.
"Go," he said, and didn't wait for Lara to argue.
She went, one-handed, her right arm tucked against her ribs at an angle that made Aaron's stomach do something unpleasant. The ladder rungs were slick with condensation and whatever else lived in Seattle's sewer infrastructure, and she was moving too slowly—every rung a controlled negotiation between her working arm and her legs—but she was moving. Aaron stood over the opening, watching the street behind them, watching the Error Logger overlay stutter and scroll through fragments of the Hunter's positional data.
Forty meters. Closing.
"Almost," Lara said from below, her voice stripped of everything except the flat mechanical focus of someone who had decided pain was someone else's problem.
Twenty meters.
"Almost faster," Aaron said.
A sound like a pressure seal releasing came from her direction, and then: "Down."
He went down the ladder so fast that the rust bit into his palms in three separate places before he caught himself on the last rung and dropped the final four feet. The impact jarred through his ankles and up into his knees, and the tunnel swallowed him whole—dark, close, and smelling aggressively of things he categorically refused to identify.
He looked up. The circle of night sky above the open manhole was still there, a pale grey disc, and through the Error Logger's overlay he could see the Hunter's signature burning like a hot coal at the edge of his perception.
Ten meters.
He reached for the reconstruction bug's energy the way you'd reach for a lighter you weren't sure still had fluid.
The response was not encouraging.
What came back was less a surge and more a trickle—the last warmth at the bottom of a cooling cup, the final pixel of a dying screen. The overlay flickered. Aaron pressed his focus against it anyway, pushing past the guttering resistance, finding the structural data the bug had been mapping since they'd entered the sewer district. The tunnel ceiling above the ladder. The stress fractures already threading through the concrete from years of subsidence and zero maintenance. The precise load-bearing geometry that the System had never bothered to model because who cared about sewer infrastructure in a post-apocalyptic game layer.
Janus doesn't. I do.
He shaped the command. Not elegant—there was nothing elegant left in the tank—but specific. A single targeted instruction aimed at the three weakest points in a rough triangle above the entrance.
He pushed.
The reconstruction bug's energy didn't so much release as collapse, like a structure that had been load-bearing for too long and simply decided it was done. The ceiling above the manhole gave a sound like a giant cracking its knuckles, and then a section roughly the size of a dining table came down in a cascade of broken concrete, rebar, and forty years of accumulated grime.
The shockwave hit Aaron in the chest and shoved him back a step. Dust poured down through the dark in a solid curtain, and the Error Logger's overlay went white with interference for three full seconds before it cleared.
The Hunter's signature was still there.
On the other side.
Aaron stood in the new dark—the manhole was gone, replaced by a rubble plug that probably weighed somewhere in the range of a lot—and breathed dust and waited.
The thump came through the stone rather than the air. A single impact, controlled, like a fist against a wall being tested rather than broken. Then silence. Then—
The ping.
It moved through the rubble and the tunnel walls and the damp air like sonar, a sound that wasn't quite sound, registering somewhere behind Aaron's ears and in the Error Logger overlay simultaneously. A slow, methodical sweep. Patient. The Hunter wasn't panicking. It wasn't even particularly frustrated, as far as he could tell. It was simply cataloguing, mapping the new obstacle with the same dispassionate efficiency it had used to dismantle every ice wall Lara had thrown at it.
Lara was leaning against the tunnel wall six feet away, her working hand pressed flat against the concrete for balance, her breathing audible and controlled. She didn't speak. Her silhouette in the near-total dark was very still.
The ping faded.
Then it came again, slightly different frequency, slightly different angle.
Triangulating.
Aaron didn't move. The rubble held. The dust that had been falling in curtains slowed to a drift, and then to individual motes settling through the dark, and the tunnel went quiet except for the distant sound of water moving somewhere below their feet and the patient, echoing geometry of the Hunter's sensors working the problem from the other side of several tons of collapsed concrete.
The dust settled.
The dark stayed.
The Warren smelled like wet concrete and other people's fear.
Aaron had been in the space maybe a dozen times, but it hit differently now—the low-hanging emergency lanterns casting amber pools across faces that had stopped pretending to be busy. Someone had warned them. The room knew. Twenty-odd survivors arranged themselves in the loose geometry of a crowd that wanted to look like it wasn't watching, which meant everyone was watching.
Marcus stood at the central table.
He didn't move when Aaron and Lara came through the inner corridor. He was already looking at the entrance, which meant he'd been looking at it for a while.
He knew we were coming. Someone on watch.
Aaron catalogued the room in the three seconds it took to cross the threshold: two people near the eastern tunnel with their packs half-loaded, a woman holding a child against her shoulder with a grip that had nothing to do with affection and everything to do with being ready to run. The air tasted like adrenaline metabolizing into dread.
Lara moved beside him, her broken arm held against her chest in a makeshift sling someone had fashioned in the tunnel from Aaron's half-shoelace and a strip of his vest lining. Every step she took was controlled and deliberate, the kind of walking that took serious concentration to make look effortless.
Marcus let them reach the table before he spoke.
"Report."
Not are you hurt or what happened. Just the one word, flat and load-bearing.
Aaron set the data drive on the table. The sound it made—a small, plastic click against scarred wood—felt enormous in the silence.
He kept the report factual. The facility. The server room. The Hunter already on-site when they arrived, not responding to their entry. The drive recovered from a sealed partition. The pursuit. The collapse.
Marcus listened with his hands flat on the table, and he did not look at the drive while Aaron spoke. He looked at Aaron. The specific quality of that attention was the kind a person developed when they'd learned that watching someone's face during a report was more informative than the report itself.
Aaron kept his face neutral and his voice even and thought about nothing whatsoever.
When he finished, Marcus finally looked down.
He picked up the drive between two fingers, held it up to the nearest lantern. The amber light caught the casing. It was a small thing. Unremarkable. The kind of object that looked embarrassing when you were trying to justify a catastrophe with it.
"You led a Hunter right to our doorstep." Marcus turned the drive once, slowly. "For this."
It wasn't a question. The inflection was the specific one that meant I am giving you the opportunity to hear how this sounds.
"The Hunter was already at the facility," Lara said from beside Aaron. Her voice was level, but Aaron caught the slight forward shift in her weight—she was bracing.
"And yet it followed you back." Marcus set the drive down. "Not to the facility. Here."
The silence after that had texture. Aaron could feel the room recalibrating—not against them, not yet, but the distance between not yet and yes was shrinking.
Marcus straightened. He was not a large man, but he had the particular quality of people who had survived long enough in bad situations that their physical presence carried compounded interest.
"We're moving." He said it to the room, not to Aaron. "Tonight. Everything that matters, packed in one hour." Then he looked back. "Because of this."
A woman near the east tunnel exhaled—not relief, just the sound of a decision landing.
Marcus let the room absorb it for a beat. Then his attention came back to Aaron, and it narrowed to something specific and unambiguous.
"You have a reputation," he said. "Strange luck. Right place, right time. I've heard it from three different people who have no reason to agree on anything." He tapped the table once, a single knuckle. "So here is what happens next. You use that luck—whatever it actually is—to find us a new location. Secure. Away from the city center. Away from the Patch radius." A pause. "Far enough that a Hunter following your scent trail ends up somewhere that isn't here."
He let that sit.
"Or," Marcus continued, and his voice didn't change pitch or temperature, which was somehow worse than if it had, "you take your drive and your luck and you walk back out the way you came. The Hunter is still up there. The Patch window opens in—" he glanced at a handwritten chart tacked to the wall, "—thirty-one hours. You're welcome to face both."
He didn't gesture. He didn't move toward Aaron or away from him.
He just waited, with the particular patience of someone who had already decided that either outcome was acceptable, and the room held its breath around the shape of the choice.
